| Abstract: | We make the experimental comparitive research on the method of dichromic potassium of method mercurical salt and the method of immercurical salt. Adopted in some currently production government and relative teaching materials moreover. The gained data were counted and managed with methods of the single factor andlysis of variance and multiple comparison. The result inducated that theve were no obvious diffelence between the method of mercurial salt with the immercurial salt. And method of aluminum powder is more handy. |
